When ripping down the trail the last thing you need to worry about is if your helmet will protect you in a crash. Then again you dont want to be stuck wearing a full-face on every trail ride. This is why we created the Ambush the lightest & most ventilated extended coverage helmet available. Starting with protection the Ambush boasts a significant amount of extended coverage Energy Optimized Multi-Density EPS foam that manages the energy from impacts effectively & a Aramid-Reinforced Skeleton that provides extra structure for the foam. Even with the added protection though it fits comfortably with our low profile & fully integrated Mindset 360 fit system. With its five height positions this system provides unmatched adjustment while an integrated dial allows for on-the-fly tinkering. The Ambush also keeps you cool with our 4th Dimension Cooling Systems massive vents & exhaust ports so you dont have to worry about overheating—even on the hottest days. Finally we included a micro-indexing visor that quickly adjusts positions & has plenty of room for goggle storage.
